Thanks for this @fzipi I am not sure about this repo pinging the other to run the deploy. I was more thinking of a dispatch job in the coraza.io where you could specify the coraza hash to run the job. I would invite others to comment whether this is the concern of this repo or not cc @anuraaga @M4tteoP @jptosso

If the goal is to make sure every commit gets directly published, this seems OK. Otherwise, I would just use a scheduled_dispatch in the coraza.io repo to update nightly or hourly.

If there are doubts, we close and move the dialog to the other repo 🤷
